Application filed February 7, 1905. Serial No. 244,569.

To LIZ zult/mb it 71ml/ concern:

Be it known that I, JOHN I. BOND,'a citizen otl the United States, residingat'laylors Store, in the county ot' Franklin, State otl Virginia, have invented certain new and useful Improvements in Spikes; and I do hereby declare the following to be a full, clear, and eX- act description ot the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to spikes in general, and more particularly to the class of railwayspikes, the object of the invention being to provide a construction wherein any attempt to withdraw the spike by upward movement ot' the rail will serve only to anchor the spike more securely into the tie.

In the drawings forming a portion ot' this specilication, and in which like numerals of reference indicate similar parts in both views, Figure I is a side elevation showing a spike embodying the present invention. Fig. 2 is a sectional view through a railway-tie into which the spike is driven, a portion of a rail being' shown in transverse section raised from the tie and the members Ot' the spike being shown in the positions they would assume if the rail were raised from the tie.

Referring' now to the drawings, there is shown a spike comprising' a head portion and a body portion, the body including three members and a temporary binder, with one of which members the head ot' the spike is integral.

One of the members ot' the body ot' the spike includes the entire lower end portion ot' the spike, which is tapered to a point and which may have any desired cross-sectional shape, although in the present instance it is rounded. From one side of the point portion 5 said member extends upwardly and is gradually increased in thickness, this upwardlysextending portion being illustrated at 6, and there being at the base of said portion, or the upper end of the point portion, a shoulder 7.

A second member ot' the body of the spike is illustrated at and corresponds in every detail to the portion 6, the lower end of the member IO in practice resting upon the shoulder T. The portions 6 and 10 are spaced apart throughout their lengths, and the interspace between them 1s gradually narrowed upwardly.

The third member of the body Ot' the spike is in the form otl an inverted wedge in that its major end is disposed downwardly, so that it initially or normally rests upon the shoulder 7, and upon the upper or minor end of the wedge is the portion 12 ot' the body which carries the head I3 and which portion 12 is flush with the side faces of the portions 6 and 10 when the wedge is upon the seat or shoulder 7.

In practice the several members of the body are held together by means otl a band 14: Ot' such arrangement that it will normally hold the parts close together, but will yield to slight outward pressure. This band may consist of a strip ot` block-tin wrapped about the spike and retain its place only by reason of its own stitfness.

The spike is driven in the usual manner, and any upward pull upon the head of the spike will draw the wedge upwardly t0 force the parts 6 and 10 apart, so as to expand the body oi' the spike and force the upper ends ot' the parts 6 and l() outwardly beyond the face ot' the portion 12. The spike being driven into the tie beyond the upper ends o't' the portions 6 and IO, the latter prevent withdrawal ot the spike, as will be understood.

It will be understood that in practice modilications Ot' the specitic construction shown may be made, and any suitable materials and proportions may be used for the various parts without departing from the spirit ot' the invention.

IVhat is claimed isA A spike comprising a body includinga point member having' an upward gradually-broadened extension and a shoulder at the base thereof, a loose upwardly-broadened member exposed with its minor end upon the shoulder, an upper member having a downwardlybroadened extension disposed between the second member and thcextension of the first mem ber and a head carried by said upper member.

In testimony whereof I aitix my signature in presence of two witnesses.

JOHN I. BOND.
